Elitebook 8470P Switchable graphics

So I've been looking around to see how to get it to work. I've looked online about this and most of the information I find is either misinformed or there are definite claims about the Elitebook's "switchable graphics".

So far I've tried to install the official drivers, but I cannot install the Intel graphics as mine doesn't meet the requirement. I looked in Device Manager and anything Intel HD isn't displayed. Just the AMD Radeon.

The BIOS gave me nothing about switchable graphics. Other HP forum threads have suggestions which I have already followed many times and yielded nothing. According to HP Partsurfer from the serial number, this is my mainboard: 686040-001

Did HP do something to the BIOS without anyone's knowledge? I was certain for sure that there'd be an option to change it but so far nothing. The BIOS is F.66.

 

The internal Intel card is not available.

You only have the dGPU.

 

I had a feeling this was the case. Everywhere I looked there was either "Yes it has switchable graphics" or "No, it doesn't." on any forum, even the official HP forum which is kind of useless. Shame.
